LUBRICTING SYSTETJI.

,cesante- Specification of Letters Patent.

Patented Feb., 18, 1913.

Application led May 3, 1929. Serial No, 493,632.

To all whom it may con-cem Bc it known that I, ROBERT A. Moline, acitizen of the United States, residing at lt/Iilwaukee, in the count)7of Milwaukee and State of lllisconsin, have invented a certain new anduseful improvement in Lubricating Systems, for' which the following is aspecification.

This invention relates to improvements in circulating s vstems forlubricating bearings.

The object otl the invent-ion is to provide a. means whereby anycessation of tiow of oil to the individual bearings can be easilvdetected. This is accomplished b v causing part of the oil Jfrom thebearings to pass through a transparent chamber. n this wav any air whichmay pocket at the bearing and prevent flow of oil,is vented.

A clear concept-ion of the invention can be. obtained bv referring tothe accompany-A ing drawing in which like reference characters denotesimilar parts.

Figure 1 is a central vertical section ot a casing carrying a bearingand a transparent leak-ott tlow detector. Fig. 2 is a similar section ofa modified tiow detector.

The shaft 1 passes through the gland 22 and'has the reduced section 2which bears in the shell 3. The shell 3 and gland 22 are supported bythe casing 8 which forms the chamber 25.

The pipe 5 leading to a pump si and from thence to the pipe G. connectswith a passage T passing through the casing S. A passage 9 leading fromthe. passage 7 in a vertical direction, connects with a passage 10 inthe shell 3, which in turn connects with the annular chamber 11 Withinthe shell A passage 14 in the shell 3-runs parallel with and above theshaftI 1 which forms one wall of passage 14. Passa-gek 12 in shell 3connects the annular chamber 11 with the passage 14.

The passage 13 in the shell 3 extends vertically above the chamber 11 atits high` est point and connects with a passage 17 through the casing 8.A pipe 15 connects passage 17 with 'a port 21 in the base 19 which has adischarge opening 20 into the chamber 25 in the casing 8. A verticalreturn pipe` 23 connects with the port 21 at its lower end, the otherend being bent downwardly and direct-ly toward the opening 20. The base19 is provided with a glass tube 1S upon and over which the cap 16 isdrawn by being screw-threaded into base 19, thus inclosing the pipe 23in a chamber which connects with the chamber 25 through the dischargeopening 20. The chamber 25 in turn exhausts through drain 211 forremoval of the oil after passing from the bearing.

-In operating the device, the oil is admitted to the pump 4 through thepipe into the passage 7. From the passage 7 a part of the oil is forcedup through the passages 9, 10, to the annular space 11 about the shaft.rllhe greater vpart of the oil leaves the space 11 through passages 12,1%, passes along the shaft 2, and is thus distributed to oil thebearing. The oil in space 11 which is not discharged in this Way; isforced up the passages 13, 1f?, through the pipe 15, the port 21 and thepipe 23. Upon leaving pipe 23 it is precipitated las a leakotf flowthrough the discharge opening 20 into the channel 25. Duringprecipitation the flow can be observed through the glass 18. As theoilfrom pipe 23 and passage 14 drops to the bottom of chamber 25 incasing 8, it is drawn ott through the drain 24. A How ot' oiliat'pipe 23indicates that the bearing is being properly lubricated,n While no flowat that point, or Jfrothy flow, indicates lack of oil supply to thebearing or heating at the bearing with consequent generation of gases.

A modification of this device is made possible b v making the inlet andoutlet ports in the casing S concentric bycounterboring passage 17 toform the recess for receiving the lower screw lthreaded end ot base 19.A nipple 26 is provided to screw into the upper end of the passage 17 atthe bot-tom of the counterbore and pipe 23 is fixed into the upper endof the nipple instead of being attached within base 19. The pipe 23 isthen bent aside, then upright 4and then reversely bent at. the top todeliver downwardly as bet'ore. The lower and upper ends of the pipe arein line and both terminate downwardly. A downwardly inclined passage 27is formed to lead from the counterbore into the chamber 25 of the casing8 to serve as a drain.,

Vents 2S are formed in thecaplt above the transparent tube 18 and thesetake the place of the, separate vents Which have to ne tornwl in chamber25 of casing S.

It should be understood that -it is not 'de sired tube limited to theexact details et construction shown and' described, for obviousmodifications will occurl to a person skilled in the art. Y

lt is claimed and desired to secure by Letters Patent:
